Ancient tools and fossils have been discovered that may provide insight into the mysterious "hobbit" species. The findings, which include stone tools and a small arm bone, are believed to be from a significant time period, potentially over 1 million years ago, and may indicate that multiple human ancestors coexisted. The discoveries were made in Indonesia, specifically on or near an island where the "hobbit" species, also known as Homo floresiensis, is thought to have lived.
